Right; the Adapter's insert() method accepts only one tuple in its
associative array argument. If you are doing an extended insert for
many rows, you should format the full SQL statement as a string, and run
it with the Adapter's query() method.
$sql = "INSERT INTO myTable ( id, field_1, date ) VALUES
( 301, 40971, '2007-10-04 04:00:19' ),
...
( 301, 40990, '2007-10-04 04:00:19' )";
$db->query($sql);
Note that you can ignore the Statement object returned by this method in
this case. The query() method is just a shortcut for prepare() and
execute(). It doesn't have to be a SELECT query, it can be any other
SQL statement type (provided the statement supports being prepared). In
this case you have no need to execute this statement more than once, so
you don't need to save the Statement object returned from query().
Perhaps there is a need for a new method insertMulti() or something like
that, which would accept an array of associative arrays, and format the
SQL appropriately. Feel free to submit a JIRA issue for this.

Subject: [fw-general] About massive inserts
Hi All,
We are currently developing an application where we need to
insert a big amount of data (thousands of records), we are connecting to
a PostgreSQL (8.1.6) database through PDO (pdo_pgsql ) the query looks
pretty much like this:
INSERT INTO myTable ( id, field_1, date ) VALUES
( 301, 40971, '2007-10-04 04:00:19' ),
( 301, 40972, '2007-10-04 04:00:19' ),
( 301, 40973, '2007-10-04 04:00:19' ),
( 301, 40974, '2007-10-04 04:00:19' ),
....
....
....
....
( 301, 40990, '2007-10-04 04:00:19' );
It works when we execute the query directly on the database, but
when using the _db methods like query, insert or even fetchRow, we
always get the same error: Syntax error: 7 ERROR: syntax error at or
near "," LINE 1: ...ate ) VALUES ( 303, 41471, '2007-10-04 04:30:45' ),
( 303, 4...
So the question is, what would be the best option to insert this
information? Seems that the insert method does not support associative
arrays to load all of the info there.
Thanks a lot for the help!
Camilo
